地層の形成や地形発達のプロセスに注目し，地球表層環境のダイナミクスや変遷を議論するため，分野の垣根を越えた研究発表を募る．手法やあつかう時間スケールを問わず，野外観測・実験，理論に基づいた地形・堆積物・堆積岩組成・流体（河川・波浪・土石流・乱泥流・火砕流など）の研究を対象とする．海底ジオハザード（海底地すべり・パイプラインや光ケーブルへの洗掘や液状化等）や資源探査の観点からの議論も歓迎する．
本セッションでは，日本語を母語とする学生等の発表や活発な議論を促すため，使用言語を日英併用とする．発表言語は英語か日本語のいずれかとし，発表スライドおよびポスターは英語表記もしくは日英併記で実施する．非日本語話者の聴講や英語での発表も歓迎する．なお，このセッションは日本語セッションであるが，英語セッションとして提案されているIUGS傘下のTask Group，TGSGによる「Submarine geohazards and their their application」と連携している．

Transportation and sedimentation of earth-surface materials - the latest results of multiple research fields, including engineering and earth sciences- are essential to understanding landscape evolution and erosion dynamics. Any research on sedimentology and sedimentary petrology, the interaction between fluid, sediments, and geomorphology, is focused in this session. Interdisciplinary discussions of science, disaster prevention, resource exploration, and marine geo-hazards, such as submarine slide, washout and seabed liquefaction of pipeline and optical cable buried sediments, are also welcome to this session.
This session will be conducted in both Japanese and English to encourage presentations and active discussions by students and others whose native language is Japanese. Presentations may be given in either English or Japanese, and presentation slides and posters should be prepared in English or in both Japanese and English. Non-Japanese-speaking participants and presentations in English are also welcome. Although this session is categorized as Japanese and English session, it is coordinated with the IUGS-affiliated task group (TGSG) session titled "Submarine geohazards and their their application", which has been proposed as an English-language session.
